Answer:
A. 2
Read Explanation:
A typewriter usually has two spool shafts.
The ribbon spools (the parts around which the ribbon containing the typing ink is wound) are mounted on these shafts.
One can be seen on the left and the other on the right.
As you type, the ribbon unwinds from one spool and contracts onto the other spool, allowing the ink to fall onto the paper.
It will also reverse direction as the ribbon runs out.
